![]() This has been quite difficult, as typically, just a few seconds after trying to unsuccessfully activate Bluetooth for the first time, the kernel crashes: The tablet becomes hung/unresponsive, and I get kicked out of 'adb shell' with this message: error: protocol fault (no status) Also, I noticed that with the original stock Android 4.1.1, the WLAN driver (compiled statically into the kernel) states in dmesg log: MT5931 SDIO WiFi driver (Powered by Rockchip,Ver 2.07) init. I have finally managed to create dmesg and catlog output after trying to activate Bluetooth: see attachments. Hello again, final update from me before the weekend. As I will only have time to look into this again after the weekend, please take your time - no need to hurry.Īnd in case it looks like there is no easy remedy, I think we'll simply stay with the stock 4.1.1 ROM for this device. Please find both catlog and dmesg output with this setup attached. For WLAN, the issue seems to be: 02-13 19:14:28.740 E/wpa_supplicant(1815): wlan0: Unsupported driver 'wext' for Bluetooth, Idn't even find any error messages, but it's simply not working. Hello Oma, bad news: With the updated model fix from post 15, things are even worse: Neither WLAN nor Bluetooth now works, and we have a lot of error messages about OutOfMemory and OpenGL renderer in the catlog. Hopefully this will keep the Ventos MTD layout - otherwise now I at least know how to restore it. So I will now (maybe tomorrow, as it's getting close to midnight.) try to install CM 10.1 again from step 1, but keeping the stock recovery img. Thanks a million for your kind help! OK, I noticed that the new 'model fix' patch now additionally includes a Bluetooth kernel module! In the meantime, I have successfully recovered my old proper MTD partition setup by flashing the stock img (ST10216-2A_V05.img, see above) using RKBatchTool 1.8. Will also provide dmesg and logcat output for the Bluetooth chip once I have restored the correct (non-standard) MTD layout and reinstalled CM 10.1. Which tool do I need to use to flash the single huge stock recovery img: ST10216-2A_V05.img - 495 021 284 bytes This must not be done with RKAndroidTool, right!? I don't even know how to do this with my stock recovery partition, as it seems to expect the img file to reside in the external SD, but have a specific name in order to find it.!?
